DELlNEATOR.

SPECIFICATION forming part of Letters Patent No. 395,724, dated January8, 1889.

Application filed July 20, 1888. Serial No. 280,488. (No model.) W

T0 aZZ whmn it may concern;

Be it known that I, DAVID K. lVADE, a citizen of the United States,residing at McPherson, in the county of l\[cPherson and State of Kansas,have invented a new and useful Improvement in Delineators, of which thefollowing is a specification.

My invention relates to a delineator designed to enable an object orgroup of objects at adistance to be accurately delineated upon paper;and it consists in a certain novel construction and combination ofdevices, fully set forth hereinafter, and specifically pointed out inthe appended claims.

In the drawings, Figure 1 is a perspective view of the device inoperative position. Fig. 2 is a front view of the drawing-board, to showthe manner of attaching the same to the base-plate. Fig. 3 is a sideview of a portion of the device, partly in section. Fig. 4. is a"ertical transverse sectional view of the vertical shaft.

Referring by letter to the drawings, A designates a base plate or bar,which is dovetailed in section and is arranged on a suitable tripod orstand, B; and C designates a vertical standard, which is mounted at itslower end in a socket, D, 011 the base plate or bar near its rear end.

A sight-bar, E, which is provided atits opposite ends with suitablesights, e e, is mounted at an intermediate point in a fork in the upperend of the stainlard; and F represents a tubular arm, which is mountedat its rear end in a vertical slot, 0, in the standard. The adjacentfree ends of the tubular arm and sight bar are connected by the rod G insuch away as to maintain the said arm and bar parallel with each other.

In suitable registering bearings, 71 71 in op posite sides of the slot0, is mounted a spindle, K, which is provided on one en d with athumbwheel, 7., to enable the spindle to be turned at will; and Lrepresents a small drum which fits on a squared portion, 71 of the saidspindle, whereby the drum may be turned by means of the thumb-wheel.

M represents a cord, which is affixed at its ends to the sight-bar onopposite sides of the standard and passes at an intermediate point onceor twice around the drum L. It will be seen that by turning the spindlethe cord M is operated so as to elevate or depress the front end of thesight, to enable the same to be directed toward any object in a givenvertical plane, and as the standard is swiveled the sightbar may beswung around freely to enable the entire field to be covered.

' N represents a pointer, which is arranged in the tubular arin F, andis provided 011 its front end with a pencil or crayon, O, which isadapted to trace the outline of an object on a suitable surface, and inthe tubular arm is arranged a coiled spring, P, which bears against ashoulder or collar, 1), on the pointer and presses the latter forward.

Q represents a vertical board, which is provided at its lower edge witha casting, R, having a notch at its lower end, which slides 011 thedovetailed base plate or bar; and T represents small thumb screws whichare mounted in the sides of the said notch and bear at their inner endsagainst the plate or bar, to enable the vertical board to be locked inthe desired position. It will be seen that means are thus provided toenable the vertical board to which the drawing-paper is adapted to beapplied to be arranged at any desired distance from the vertical shaft0.

The operation of the device is as follows: Having adjusted the tripod inthe desired position, the sight-bar is successively directed towarddifferent salient points of the object to be represented, and the pencilor crayon is allowed to make suitable marks at the various positions ofthe sight-bar; or the butline of the said object may be followed by thesight bar, while the point of the crayon or pencil is in contact withthe surface of the paper 011 the board, thereby drawing the outline ofthe said object on the paper.

The size of the drawing in proportion to the size of the original or theobject represented depends upon the distance of the drawing device fromthe object and the distance of the vertical board from the standard C,as will be readily understood.

Having thus described the invention, I claim 1. In a delineator, thecombination of a standard mounted in a suitable socket, the sight-barmounted on the upper end of the standard, the tubular arm pivoted at oneend i to the standard and connected at the other end to the free end ofthe sight-bar, whereby the tubular arm and the sight-bar are heldparallel, and the pointer arranged in the tubular arm and provided. atits front end with a suitable pencil or crayon adapted to bear against avertical surface, substantially as specified.

2. In a delineator, the combination, with a base plate or bar arrangedon a suitable stand or tripod and the vertical board longitudinallyadjustable on the said plate or bar, of the stand ard mounted in asuitable socket onthe base plate or bar, the sight-bar mounted on theupper end of the standard, the tubular arm pivoted to the standard atone end and connected by a suitable rod to the free end of the sightbar,and the spring-actuated pointer mounted in the tubular arm and providedwith a pencil or crayon adapted to bear against the said board,substantially as specified.

3. In a delineator, the combination, with a base plate or bar having avertical board arranged thereon, of the standard swiveled at its lowerend on the plate or bar, the sightbar mounted on the upper end of thestandard, the tubular arm connected to the sightbar and carrying asuitable pointer, and the cord affixed at its ends to the sight-bar onopposite sides of the standard and passing at an intermediate pointaround a suitable drum or pulley, substantially as specified.

at. In a delineator, the combination, with a suitable base plate or barprovided with a suitable vertical board, of the standard swiveled on thesaid plate or bar and provided with a vertical slot, 0, the spindle K,mounted in registering bearings in opposite sides of the slot 0 andprovided with a thumb-wheel and a drum, the sight-bar provided withsuitable sights, the cord attached at its ends to the sight-bar andpassing at an intermediate point around the said drum, the tubular armmounted in the lower end of the slot and connected at its free end tothe sight-bar, and the pointer mounted in the tubular arm and providedwith a suitable pencil or crayon, substantially as and for the purposespecified.

5. In a delineator, the combination, with the dovetailed base plate orbar A, provided with a socket, I), the standard mounted in the socket,the sight-bar mounted on the standard, the tubular arm mounted on thestandard and connected to the sight-bar, and the pointer arranged in thetubular arm, of the vertical board provided with a depending castinghaving a dovetailed notch fittin snugly on the base plate or bar, andthe thumb-screws arranged in the sides of the notch and bearing againstthe plate or bar to lock the board in the desired position,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto afiixedmysignature in presence of two witnesses.
